Protection from degradation1

  • Early neutrophil recruitment impairs clearance by chemically damaging protective antibodies

    Where this hypothesis actsExtracellular antibodies in susceptible older-adult tissues exposed to neutrophil oxidants

    What is proposedPreserve the opsonic function of local IgG

    With whatProtein or peptide as the agent

    HowRestrain early neutrophil recruitment; test causality by replacing damaged IgG with an equal concentration of intact, specificity-matched IgG

    Possible resultPossible restoration of viable-pathogen clearance without reopening vessels or reducing recruitment
